﴿ وَلَقَدْ أَرْسَلْنَآ إِلَىٰ ثَمُودَ أَخَاهُمْ صَٰلِحًا أَنِ ٱعْبُدُوا۟ ٱللَّهَ فَإِذَا هُمْ فَرِيقَانِ يَخْتَصِمُونَ ﴾
“AND [likewise], indeed, We sent unto [the tribe of] Thamud their brother Salih [with this message]: “Worship God alone!” and, behold, they were [split into] two factions contending with one another.”
